Answer:
Step-by-step explanation:
Given the inequality solved by a student expressed as:
-6v>42
To get v, follow the simple steps
Step 1: multiply both sides by -1
-6v>42
-1(-6v)<-1(42)
6v < 42 (Note that when you multiply both sides of an inequality by a negative sign, the inequality sign will change)
Step 2: Divide through by 6
6v < 42
6v/6 < 42/6
v < 7
Hence the range of values of v are the values of v less than 7
Since we are not given the options, you can compare the solution given with that of the student to figure out the error. The major error that may happen is the different not changing the inequality sign after multiplying or dividing with a negative value as shown.
Answer:
First one: 114
Second one: 64
Step-by-step explanation:
For the first one, you can break apart the shapes to a square and a rectangle
The square is 7 x 7 (12 - 5 = 7)
The rectangle is 13 x 5
The square is 49
The rectangle is 65
Add them together
The first one is 114
For the second one you can break it apart to a triangle and a rectangle
The rectangle is 4 x 12
The triangle is 0.5 * 8 * 4 [8 is 12 - 4 (base)]
The rectangle is 48
The triangle is 16
Add them together
48 + 16 = 64
The second one is 64
-5m - 6 >= 24
Add six on both sides
-5m >= 30
Divide by negative five on both sides
m >= -6
Ummm I think it is 2 hours and 3 miles for the van for the truck I don’t know and I don’t know
Question 1:
Choir A - 129.5 = 130
Choir B - 130.1 = 130
Choir C - 130.8 = 131
Choir D - 129.8 = 130
Answer - Choir C
Question 2:
132 = 1/2x + 2(x - 9)
= 1/2(60) + 2(60 - 9)
= 30 + 102
= 132
60 - 9 = 51
